I like knives, and Airsoft, and making things, so i put that all together and made some practice knives out of PVC. They can be used for Airsoft or other Milsim sports, messing around, or training. They are cheap, durable, light, and pretty safe.
These have no sharp edges, but do be warned, they are still not really toys, they can bruise or break bones if swung with enough force, or put out an eye if you get poked. These might also be illegal in your area, so if you really care about laws pertaining to your possession of a dull plastic knife, then follow them.
Step 1Tools and materials
As far as tools, surprisingly, not much, It all depends on the level of detail you want. Items with an asterisk* are not optional.
- *vise, bench clamp, or other clamp with a large clamping area and a really strong grip.
- *Heat gun. I use a Wagner Power Stripper. They aren't too hard to get or too expensive. Look at your local hardware store, it shouldn't be more than $30 (US). Make sure you keep the receipt, if it doesn't get hot enough to melt the PVC, then you will need to trade it in for another one. In theory, you could use a flame or a torch, but they are way hotter than you need and much more dangerous.
- Rivet gun or some other fastening tool to secure the grips.
- Sand paper
- *File, to shape the tip.
- *saw to cut the pipe
- Rotary Tool
Materials- again, items with a * are required
- *PVC pipe. I use grey 1/2 inch PVC for this blade, but all kinds work. Try different colors, and different diameters. You can use one size of pipe for the handle and another for the blade. Oh, and by the way, this is all you really need to make a really basic knife.
- PVC reducer sleeve
- Bicycle grip- I found mine on the side of the road. If you find an old crappy bike, take off the grips and use them, or go buy them. They only usually fit 1/2 inch pipe though.
